Bristol-Myers enters immuno-oncology collaboration with Kyowa Hakko KirinKyowa Hakko Kirin and Bristol-Myers Squibb announced that the companies have entered into a clinical trial collaboration agreement to conduct a Phase 1/2 combination study with mogamulizumab, an anti-CCR4 antibody and Opdivo, a PD-1 immune checkpoint inhibitor. The study, which will be conducted in the U.S., will focus on evaluating the safety, tolerability and anti-tumor activity of combining mogamulizumab and Opdivo as a potential treatment option for patients with advanced or metastatic solid tumors. Prior to this agreement, Kyowa Hakko Kirin, Bristol-Myers Squibb and Ono Pharmaceutical entered into a clinical trial collaboration agreement to study the combination of mogamulizumab and Opdivo in Japan. Mogamulizumab and Opdivo are part of a new class of cancer treatments known as immunotherapies, which are designed to harness the body’s own immune system in fighting cancer by targeting distinct regulatory components of the immune system.

Bristol-Myers, AbbVie say EMA validates for review Empliciti MAABristol-Myers Squibb Company (BMY) and AbbVie (ABBV) announced the European Medicines Agency validated for review the Marketing Authorization Application for Empliciti, an investigational Signaling Lymphocyte Activation Molecule-directed immunostimulatory antibody, for the treatment of multiple myeloma as combination therapy in adult patients who have received one or more prior therapies. The application was granted accelerated assessment by the EMA’s Committee for Medicinal Products for Human Use. Bristol-Myers Squibb and AbbVie are co-developing Empliciti, with Bristol-Myers Squibb solely responsible for commercial activities. Bristol-Myers Squibb has proposed the name Empliciti which, if approved by health authorities, will serve as the trade name for elotuzumab. The MAA is primarily supported by data from two randomized clinical trials, each combining Empliciti with a different standard of care regimen for multiple myeloma. ELOQUENT-2, a Phase 3, randomized, open-label study, evaluated Empliciti in combination with lenalidomide and dexamethasone versus lenalidomide and dexamethasone alone. The results of this trial were published in The New England Journal of Medicine on June 2. Additionally, a Phase 2, randomized, open-label study evaluated Empliciti with bortezomib and dexamethasone versus bortezomib and dexamethasone alone. These Phase 2 results were presented in an oral session at the 20th Congress of the European Hematology Association. Empliciti previously obtained orphan drug designation in the European Union. An orphan medicinal product must be intended for the treatment, prevention or diagnosis of a disease that is life threatening and chronically debilitating; the prevalence in the EU must not be more than five in 10,000. The medicine must be of significant benefit to those affected by the condition. If maintained, orphan drug designation allows sponsors to access a number of incentives including protocol assistance and receive market exclusivity for a ten-year period following approval.

Bristol-Myers: Data from Phase IIa study support further evaluation of BMS955176Bristol-Myers Squibb announced additional Phase IIa proof-of-concept data for BMS-955176, a novel investigational agent designed to prevent the maturation of HIV-1. The study findings, which are being presented in a late-breaking oral presentation at the 8th IAS Conference on HIV Pathogenesis, Treatment and Prevention in Vancouver, confirmed the antiretroviral activity of BMS-955176 when administered with atazanavir and support further development of the second-generation HIV-1 maturation inhibitor. BMS-955176 is designed to inhibit one of the last steps of the HIV-1 viral lifecycle, resulting in the release of immature non-infectious HIV-1 particles. As part of a multi-part proof-of-concept study, a two-drug combination of BMS-955176 plus atazanavir had a maximum median change in HIV-1 RNA of -2.23 log10 c/mL from baseline through study discharge. The standard of care control of atazanavir 300 mg and ritonavir 100 mg plus tenofovir disoproxyl fumarate 300 mg plus emtricitabine 200 mg in a fixed dose combination had a maximum median change in HIV-1 RNA of -2.39 log10 c/mL from baseline through study discharge. In addition, a lower dose of BMS-955176 plus atazanavir and ritonavir had a similar maximum median change in HIV-1 RNA of -2.20 log10 c/mL. Length of therapy for all treatment groups was 28 days. Study endpoints included change in HIV-1 RNA from baseline to Day 28 and from baseline to the end of the study and safety. Data from Part A and Part B of the Phase IIa proof-of-concept study support the further evaluation of BMS-955176 in novel treatment regimens such as nucleos(t)ide- and booster-sparing regimens to address key unmet needs for HIV-1 treatment-experienced patients. Two Phase IIb studies have started in 2015: a traditional dose-finding study in treatment-naive patients and a second Phase IIb study to evaluate a nucleos(t)ide- and booster-sparing regimen in treatment-experienced patients.

Bristol-Myers Squibb receives FDA breakthrough designation for HIV-1 inhibitorBristol-Myers Squibb announced that the FDA has granted Breakthrough Therapy Designation to the investigational compound BMS-663068 when used in combination with other antiretroviral, or ARV, agents for the treatment of HIV-1 infection in heavily treatment-experienced adult patients. BMS-663068 is an oral prodrug of the molecule BMS-626529 and first-in-class HIV-1 attachment inhibitor. The attachment inhibitor is designed to work differently than entry inhibitors, a current class of drugs that targets co-receptors’ activity or fusion after HIV attaches to the CD4+ host cell. BMS-663068 is thought to work at an earlier point in the replication process to prevent the virus’ initial interaction with immune cells entirely, and thus blocks its entry into the cell.
